Blue Ocean LH-30 small rotary drilling rig engineering factory direct LH-30 small rotary drilling rig mechanical engineering high efficiency, low cost and stable performance. With a belt transmission ratio, when the drill motor is caught easily burned, speed reducer easily damaged. Light is easy to shift the whole machine weighs less than 300Kg, and is broken down into two pieces, dresses, shelves LH-30 Small Rotary Drilling Rig About the rig through a high-performance motor for rotary power reducer, with cylinder for propulsion. Eliminating the hydraulic system, and thus a high mechanical efficiency, low cost and stable performance. By belt than when the drill motor is caught easily burned, speed reducer easily damaged. Lightweight easy to shift. The whole weight of less than 300Kg, and can be decomposed into two pieces, dresses, convenient shelves. LH-30 small rotary drilling engineering drilling rig can be used for construction of the scope of urban construction, railways, highways and other projects in the bolt hole, blasting holes, grouting holes and so on.
